Java final modifier keyword

I’ve been a huge fan of the ‘final‘ modifier in Java for function arguments and variables. While there’s some debate on their usefulness for performance, they definitely add in readability and understanding of code as developers are instantly notified by modern IDE’s and when they try to reassign such values as the compiler will indicate the error.

NOTE: Use of final for classes or functions often contradicts the paradigm of Object Oriented programming as you’ll be restricted from extending or overriding those items!
